Most commonly available substances that are less dense than water is oil, alcohol and plastic. In fact, a number of organic solvents such as acetone, methanol and methylene chloride are also less dense than water. In addition, a number of different kinds of polymer are "lighter" than water, too.
Hmm... potassium and sodium? :D
What else can I help you with?
Witch objects are less dense than water?
Bottle caps, twist ties (depends on shape).
Why does ice has a lower density than water?
Yes, ice is less dense than water. Ice will float on water because it is less dense than that water. Two related questions are linked below, and you can learn why ice is less dense than water by following those links.
What materials will float on water?
Materials that are less dense than water will float on it, such as wood, plastic, cork, and some metals like aluminum. Materials that are more dense than water will sink, such as most metals like iron and lead. Additionally, objects with trapped air pockets, like inflated balloons or a boat, will float due to the buoyant force of the air.
Why does some things float on water while others dont?
Some things float on water because they are less dense than water, creating buoyancy that allows them to stay afloat. Other things sink in water because they are denser than water, causing them to displace water and sink. Factors like shape, size, and weight can also affect whether something will float or sink in water.
What floats on water?
Objects that are less dense than water will float on water. This includes things like wood, plastic, and some metals. Buoyant objects displace enough water to create an upward force that helps them float.
What Items float on water?
Ones that have a density lower than 1g/cm3.
What is less dense glass or water?
Generally, glass is more dense than water. (There are some types of glass which are less dense.) You can demonstrate this by gently placing a glass full of water in the sink or tub; the glass will sink, indicating that glass is more dense than water. If the glass were to float, we would know that the glass were less dense. Try this with plastic cup; the plastic is normally less dense, and will float.
What are some planets with less density than water?
they are gas, and gas is less dense
Does adding water to a liquid make it less dense?
That depends on the specific situation. Assuming the liquids just mix, and don't have some other reaction: * Adding water to a liquid that is denser than water will result in a liquid that is less dense (than the liquid that is not water). * Adding water to a liquid that is less dense than water will result in a liquid that is more dense.
What liquid is LESS dense than wood?
Ice! Some wood is also less dense than water. Styrofoam and some plastics are also less dense than water. There is an EXTREMELY simple experiment to test for this. Any object that floats when placed in water is less dense than the water it is in.And of course sperm.
What is less dense wood or water?
Most wood seen on a common basis is less dense than water. These woods floats on water. Some more exotic woods are more dense than water and sink when placed in water.
Why some object float and other sinck in the water?
It has to do with density. If an object is less dense than water (for example, oil), it floats. If an object is more dense than water, it sinks.
What minerals are less dense than water?
Some examples of minerals that are less dense than water are pumice, sulfur, and talc. These minerals can float on water due to their low density, which is less than 1 g/cm³.
Why do some things float?
They are less dense than water. More dense things sink. Density refers to how tightly the atoms are packed.
Is there a plastic that does not float in water?
Most plastics are less dense than water and will float, but some heavy plastics, such as polyethylene terephthalate (PET) or polyvinyl chloride (PVC), can be denser than water and sink. However, these are not commonly used for everyday items.
Why does poop floats?
Feces (the technical term) are less dense than water. If an object is less dense than water, it floats. If it is more dense than water, it sinks.
How does liquid affect the height of which some objects float or sink?
Floating and sinking is related to density - if something is more dense (i.e. has more mass per volume) than the fluid it will sink, and if it is less dense then it will float. This is why wood floats in water, and helium balloons float in air - helium is less dense than air and wood is less dense than water. Steel ships float because, although they are made of steel which is more dense than water, the air inside them is less dense than water so the overall effect is floating.
